How To Avoid LRAD

To avoid LRAD (Long Range Acoustic Device) effects—used by law enforcement and military for crowd control or communication—it’s important to understand what LRAD is and how to protect yourself.

🔊 What Is LRAD?

LRAD is a powerful directional speaker system that emits high-intensity sound waves. It is used to:

Broadcast messages over long distances
Deter crowds with pain-inducing sound at high decibels

At close range or high volumes, LRAD can cause:

Hearing damage or loss
Nausea, dizziness, disorientation
Headaches and ear pain

✅ How to Avoid or Minimize the Effects of LRAD

1. Distance Yourself

The further you are, the lower the impact.
LRAD is directional—move out of its line of projection if possible.

2. Protect Your Hearing

Wear high-quality earplugs or noise-canceling earmuffs.
Doubling up (earplugs + earmuffs) offers better protection.

3. Use Physical Barriers

Solid walls, buildings, or even vehicles can block or dampen the sound.
Turn your head and cover your ears if no protection is available.

4. Stay Informed

If you’re attending a protest or public event, check for police presence or surveillance.
Avoid areas with known crowd dispersal equipment.

5. Wear Protective Gear

Specialized acoustic-resistant headgear is used in industrial and military settings.
DIY solutions like foam earplugs and scarves can help, but are less effective.

🚫 Know Your Rights

In many regions, misuse of LRAD at dangerous decibel levels may be challenged on grounds of excessive force or health violations. Legal actions have been taken in some cases.
